In this study, we investigated responses of the Photochemical Reflectance Index (PRI), and
Normalized Difference Vegetation Index (NDVI) to gradual dehydration of several Antarctic …

Five macrolichens of different thallus morphology from Antarctica (King George Island) were
used for this ecophysiological study. The effect of thallus desiccation on primary …

Lichens are symbiotic organisms that are well adapted to desiccation/rehydration cycles.
Over the last decades, the physiological background of their photosynthetic response …

In many polar and alpine ecosystems, lichens of genus Umbilicaria represent dominant
species forming community structure. Photosynthetic and spectral properties of the lichens …

Antarctic lichens have been used as indicators of climate change for decades, but only a few
species have been studied. We assessed the photosynthetic performance of the fruticose …

Lichens are successful colonizers in extreme environments worldwide, and they are
considered to have played an important role during the evolution of life. Here, we have used …

There is a need for non-invasive monitoring of temporal and spatial variation in hydration
and photosynthetic activity of red-listed poikilohydric autotrophs. Here, we simultaneously …

Interspecific differences in desiccation tolerance of selected Antarctic lichens: Analysis of
photosystem II effectivity and que Page 1 CZECH POLAR REPORTS 12 (1): 31-43, 2022 …

Main conclusion Drought tolerance was greater in the whole lichen than in its isolated
photobiont. Cell turgor state has an influence on the functionality of photosynthetic process …

Lichens survive harsh weather of Antarctica as well as of other hostile environments
worldwide. Therefore, this investigation is important to understand the evolution of life on …
